This was brought up some months ago, and there has been no response/explanation from anyone.
In Rapidweaver 7.3.3, on OSX 10.11.6, the Media Browser displays Photos automatically. However, I cannot add other folders.
Since I also still use iPhotos, the Media Browser is therefore useless.
Since this is definitely not a feature, for me it is a bug.
Why is it happening, and is there a workaround?
